Description: This function checks the connectivity and length of all rigid elements, RBE2 and RBAR. Rigid bodies that exceed the length criteria of the user or that are loose, zero-length, double dependent, cyclic, or redundant are highlighted.
Usage:
1. DSI prompts:
> FIND RIGID LINKS LONGER THAN CERTAIN LENGTH? (Y/N)
? YES
> ENTER LENGTH CRITERIA
• Any real number greater than zero.
NO
2. The user has the option to place failed elements into new parts. If the user opts to place the failed elements into a new part, DSI will generate the following part names:
r.xlong • Checks for RBE2s that fail length check.
r.duplic • Checks for degenerate RBE2s.
r.cyclic • Checks for two RBE2s sharing the same two nodes in an independent/dependent node loop.
r.double • Checks for RBE2s with double dependent nodes.
r.loose • Checks for loose connections.
The user returns to the MODEL CHECKER menu
